Reconstruction at the wavelengths of recording is obligatory in color holography. If recording is made on silver halide light sensitive materials, a shrinkage of the layers causes different shifts of diffraction peaks towards lower wavelengths. The shrinkage is compensated by suitable swelling before final drying of the holograms. The report presents recent results obtained for swelling of holograms recorded at wavelengths in the red, green and blue spectral regions for an ultra-fine grain panchromatic silver halide emulsion with 10 nm average size of initial silver halide grains. The cases of successive and simultaneous irradiation of a single silver halide plate with the three wavelengths used are compared. Experiments on repeatability of the swelling procedure are also provided. Diffraction efficiency of bleached single exposure volume reflection holograms in red, green and blue has values higher than 50% for exposure energy of 2.0 mW/cm2 both for the CW and pulse lasers.
